These are also the largest numbers I've had to store, however 64 bits should suffice for a very very long time for twitter id's. If everyone on earth (assuming 6 billion people) tweeted 100 times per day, it would take over 84 million years to overflow 64 bits.

But if you had 84 million inhabited planets, with 10 tweets a day, it would only take 10 years (correct me if my math is wrong).
